A reactor coolant leak was fixed at the 1,268 MW Perry nuclear power plant in Ohio just days after tritium was found in groundwater outside of the plant.
According to the Cleveland Plain Dealer, workers with FirstEnergy Nuclear Operating Co. made the repairs overnight on Jan. 22. The leak was first discovered Jan. 20 when cameras caught a small spray of water and steam coming from a pipe located in the under drain system in the Auxiliary Building.
Groundwater samples showed tritium levels of 46,000 pCi/l. The U.S. Environmental Protection Agency limit for groundwater is 20,000 pCi/l. Other groundwater monitoring stations around the plant did not show any tritium, the article said.
